5 Simple Ways You Can Harvest Rainwater at Your Home
Apr 26, 2017
Shortage of water isn’t a new issue. Summers are particularly tricky as it becomes difficult to manage chores without enough water. The rivers and other sources of water dry up during the season, and there isn't enough water to meet all our requirements. In spite of this most of us take water for granted until there’s a shortage of water at home.
What can you do? You can’t do anything about the source of water. But, what you can easily do is save water in every way possible and voluntarily opt for rainwater harvesting in your home. Rain is a free source of water and it goes for a waste when we don’t preserve it. It’s not a difficult task if you put your mind into it. You just have to get the right containers and technology to ensure that you have an uninterrupted supply of water throughout the year.
So, in this monsoon take a pledge not to waste rain water and make all possible efforts to collect and use it. Here are 5 simple ways you can harvest rainwater at home.
1) Rooftop rainwater harvesting through recharge pit
This technique works best for buildings with a rooftop area of 100sq.m. Your building should be constructed in a way so that the shallow aquifers can be recharged. Recharge pits can be of any size ranging between 1-2 m wide and 2-3 m deep. It has to be filled with boulders, gravel and coarse sand. You’ll have to install a mesh on the roof to prevent leaves and solid debris from entering the pit. You’ll have to clean the top layer of sand periodically to ensure the recharge rate remains high.
2) Rain garden harvest method
To create a rain garden, you’ll have to create a sunken landscape with native plants, local soil and mulch to remove pollutants from water and let it percolate into the ground. Native plants are easy to maintain throughout the year, and their deep roots encourage infiltration and absorption of nutrients. This will also have a positive impact on the environment.
3) Rain barrel
This is the easiest method using which you can harvest rainwater in your backyard. Use an old trash can or drum to make a rain barrel and link it to a pipe. The drums or barrels help in collecting rainwater from the rooftop of your house. Use a tight-fitting lid to cover it to ensure it doesn’t become a breeding ground for mosquitoes. You can also add a tablespoon of vegetable oil to the water to coat its surface and kill larvae by cutting off oxygen.
4) Rain saucer
A simple DIY rain saucer will also serve the purpose if you can place it together. Rain saucers look like upside-down umbrellas, which you can create out of asbestos sheets or sturdy plastic. The saucer unfolds to form a funnel that collects rainwater and fills the container attached to it. It also reduces the chances of contamination.
5) Splash block
This will help you divert flowing rain water from your building’s foundation. You can use a piece of plastic or concrete to create a splash block, which is approximately rectangular in shape, placed below the downspout that carries rainwater from your roof. It will absorb the force of water that’s diverted from the roof and will also prevent the creation of holes in the garden due to the force of pouring water.
With so many ideas at hand, you must begin your rainwater harvesting project today because monsoons are not too far away!
